Answer:
84
Step-by-step explanation:
The least common denominator of the 7, 6, 12, which are the denominators of the fractions in the given linear equation, is the least expression or number that is divisible by 7, 6, 12.
To find the LCD, express each number as factors of itself as follows:



Find the product of the highest terms
The product = LCD = 
LCD of 7, 6, 12 = 84
Answer:
Zack earned £125, Jack earned £75, and Sasha earned £50
Step-by-step explanation:
Considering the number of leaflets delivered
Zack 50%, Jack 30% and Sasha 20%
Total delivered = 50 + 30 + 20 = 100%
If they earn £250 on the 100% delivery, then each will have as shown below
Zack = (50/100)*250
= 5*25
= £125
Jack = (30/100)*250
= 3*25
= £75
Sasha = (20/100)*250
=2*25
= £50

To find out the answer, we would have to try and divide all the numbers.





Answer:
S 32, W 128, M 96
Step-by-step explanation:
W = 4S
S = 1/3M, or 3S = M
S + W + M = 256
Substitute
S + 4S + 3S = 256
8S = 256, S = 32
S = 32
W = 4S = 128
M = 3S = 96
